By contrasted with silica gel, the corn hull desiccants by hydrolyzation method and heat treatment method have advantages as stabilization on moisture adsorption, less water of reversible adsorption and high moisture adsorption ratio in high humidity. These desiccants have disadvantages as lower moisture ratio than silica gel in low humidity and slower moisture adsorption speed than silica gel. The corn hull desiccant by derivation method has advantages as high moisture adsorption ratio, high moisture adsorption speed, stabilization on moisture adsorption and hardly any water of reversible adsorption.
